Im trying to get gpio to work on a 3.1 kernel
on boot im seeing the following messages
The GPIO_CFG4 is 0x55555, not equal to 0x155555, maybe using by boot!does anyone have any idea what this means?
The GPIO_CFG5 is 0x15555555, not equal to 0x0, maybe using by boot!
also, ive built gpio support w/ sysfs into my kernel.
Id like to do be able to do something like the following...
$cd /sys/class/gpioits not working, so somethings not right here; I cant change the gpio values, and that gpio error message during boot looks suspicious. can anyone please help me figure out whats going on here?
# this creates 'gpio7' directory, exports gpio for use
$echo 7 > export
#setup gpio7 for output, and change its value to '0'/'low'
$echo "out" > gpio7/direction
$echo 0 > gpio7/value
#try to check value, should be zero, but value always stays 'high'/'1'
